Check if Python is installed

This section explains how to install Python on your computer. The ASReview software runs with Python in the background. Therefore, running ASReview requires having Python 3.6+ installed. Knowledge about Python is not necessary to run ASReview. To start ASReview you have to open the Command Line Interface (CLI). The CLI allows you to interact with your computer directly and is operated by text inputs (commands), rather than through a graphical interface with clickable buttons. If this is the first time you’re working in the CLI, don’t worry, as this tutorial will guide you through all the steps.

Several users encounter issues with installing ASReview since a recent upgrade of Windows due to an issue with the numpy dependency. Windows recently released a new version which, unfortunately, breaks all kinds of packages, including numpy. Numpy is a library for Python used by thousands of software packages including ASReview. If you recently upgraded windows you might encounter an error about numpy when installing ASReview. If so, you can find a solution on our Github page. Please let us know (via Github) if it solved your issue or if you found a different solution – MANY THANKS!
